12-Bit, 600Msps, High-Dynamic-Performance
DAC with LVDS Inputs
General Description
The MAX5889 advanced 12-bit, 600Msps, digital-to-
analog converter (DAC) meets the demanding perfor-
mance requirements of signal synthesis applications
found in wireless base stations and other communica-
tions applications. Operating from 3.3V and 1.8V sup-
plies, the MAX5889 DAC supports update rates of
600Msps using high-speed LVDS inputs while consum-
ing only 292mW of power and offers exceptional
dynamic performance such as 79dBc spurious-free
dynamic range (SFDR) at f
OUT
= 30MHz.
The MAX5889 utilizes a current-steering architecture that
supports a 2mA to 20mA full-scale output current range,
and produces -2dBm to -22dBm full-scale output signal
levels with a double-terminated 50Ω load. The MAX5889
features an integrated 1.2V bandgap reference and con-
trol amplifier to ensure high-accuracy and low-noise per-
formance. A separate reference input (REFIO) allows for
the use of an external reference source for optimum flexi-
bility and improved gain accuracy.
The MAX5889 digital inputs accept LVDS voltage lev-
els, and the flexible clock input can be driven differen-
tially or single-ended, AC- or DC-coupled. The
MAX5889 is available in a 68-pin QFN package with an
exposed paddle (EP) and is specified for the extended
(-40°C to +85°C) temperature range.
Refer to the MAX5891 and MAX5890 data sheets for pin-
compatible 16-bit and 14-bit versions of the MAX5889.
